2006–07 Belgian First Division

The 2006-07 season of the BelgianFirst Division began on July 28, 2006 and concluded on May 19, 2007. The championship was decided in the penultimate round on May 12, 2007, when Anderlecht moved five points clear of runners-up Genk to retain the title and win their 29th League Championship. At the other end of the table, the struggle to avoid automatic relegation went on until the final round, and it was Lierse who eventually prevailed. Having spent the entire season at the bottom of the standings and only just managed to close an eleven-point gap up to 17th, the Lier side won their last game to climb past Beveren and send the latter down to the Second Division. However, Lierse went on to lose the playoffs and was relegated anyway.

April 15 - At Lokeren, assistant coach Rudy Cossey announces he will leave the club after 12 years and take up the job of head coach at second division team Oud-Heverlee Leuven next season. In Leuven, Guido Brepoels had announced a few weeks earlier that he was leaving at the end of the season to take up the job at another second division team, KVSK United.

April 28 - As both Club Brugge and Charleroi are still in the running for the fifth place and thus also possibly a ticket for European football next season, chairman Abbas Bayat decides to fire coach Jacky Mathijssen. Later that day the supporters chant Mathijssen's name during the match between Charleroi and Lokeren to express their unhappiness with Bayat's decision. Philippe Van de Walle is the caretaker for the four remaining matches of the season.
